Atmospheric dynamics Research InfraStructure in Europe

The project

The aim of the ARISE-FR project is to integrate observation and research activities on the atmospheric dynamics from the troposphere to the lower thermosphere in order to improve synergies, visibility and sustainability of the French infrastructures involved in this domain. It is based on the European research infrastructure project, ARISE (Atmospheric dynamics Research InfraStructure in Europe, led by France. The objective of ARISE is the characterization of the disturbances in the different layers of the atmosphere, the layer interactions and impacts on the climate with a spatio-temporal resolution never obtained previously. This project is expected to make significant progress on atmospheric disturbance modeling with applications related to medium range (month, season) weather forecasts, climate and extreme weather monitoring for civil safety. French activities are led by the Atomic Energy and Alternative Energies Commission (CEA / DIF) leader of the ARISE1-FP7 and ARISE2-H2020 projects, the CNRS (LATMOS) and the University of Versailles.

Products available

ARISE-FR proposes three modules of specific products representing complementary domains:

  • Module 1: Tool for the comparison between the temperature profiles provided by the models of the European Center for Medium-Range Weather Forecasts (ECMWF) and lidar data of the Haute Provence Observatory (OHP).

Studies performed in the framework of the ARISE project have highlighted the important differences that could exist, between the vertical profiles of temperature and wind deduced from atmospheric circulation models (widely used by the infrasound community for propagation simulations in particular) and the profiles, obtained from lidar, radar and / or other technologies in the ARISE reference stations. This result – widely confirmed by the numerous observations obtained by the ARISE partners – encouraged the development of this tool, dedicated to the systematic comparison between temperature profiles measured by Lidar at the OHP (time period selected on line) and the profiles deduced from the ECMWF Era-Interim reanalysis. The main application is the validation of models. The obtained profiles are also of interest for simulations in different domains (infrasound propagation, atmospheric modelling for example).

  • Module 2: Notification of volcanic activity in the Etna region, from the far-field infrasound data of the OHP station. These data are of interest to the scientific community involved in volcanic eruption studies. The methods of remote detection of volcanoes by this technology can be applied to the monitoring of other volcanoes. These infrasound data can also be used for the study of other phenomena detected by the infrasound technology.
  • Module 3: Comparisons of OHP multi-technology observations (infrasound, LIDAR and satellites) for the study and characterization of gravity waves.

The following data are provided: (i) potential energy estimates derived from LIDAR temperature measurements, (ii) potential energy estimates derived from COSMIC satellite measurements, and (iii) wind and potential energy estimates derived from the MERRA model. These data are of interest to the scientific community studying gravity waves and their impact in the different layers of the atmosphere.
